PART NO: 51621. REVISION 6 - OCTOBER 2016
1. If the door is hard to operate in
ANY DIRECTION
check that the door is not jamming in the guides.
Check:
a) the guide clearances;
b) that guides are plumb;
c) that the guide surfaces are clean and
free from oil;
d) that locking bars are the correct
length; and
e) that weatherseal is correct length.
2. If the door is hard to operate in
ONE DIRECTION
, the
spring tension requires adjustment. See Step 2.11.
a) If the door is hard to lift, but tends to drop, then
increase the spring tension.
b) If the door is hard to close, but tends to rise,
then decrease the spring tension.
3. If the door rolls up crooked as shown right then:
Check:
a) Brackets are level, refer to Step 2.
b) Axle is centralised.
c) Guides are plumb, refer to Step 7.
To centralise the axle - NOTE:
these instructions are for the example illustrated - the axle needs moving to the right
(to move left they would be vice versa).
NOTE:
Springs are tensioned and can cause injury.
With the door rolled up tie two ropes around the door roll approximately 300mm from each end, as a safety
precaution. With the door rolled up, loosen one “U” bolt, then go to the other end of the door and with a firm hold
on the axle, with a pipe wrench, loosen the second “U” bolt and move the axle to the right (the direction of the
arrow in diagram ). Move the door distance “X” in diagram.
Re-tighten
one of the “U” bolts before releasing pipe
wrench then
re-tighten
the other “U” bolt.
If the door is stiff to work or rattles over lead-in on top of guide, then refer to Step 7.

1. With the door rolled up tie two ropes around the

least 450mm long.
3. Loosen the “U” bolt nuts at both ends and
KEEP A
FIRM GRIP ON WRENCH
.
4. Rotate the axle in the required direction (see
diagram).
